For this case we have a function of the form
y = h (x), where
h (x) = 25 ^ 2-1

We know that, by definition of perfect squares difference we have:


a ^ 2-b ^ 2 = (a + b) (a-b)

So:


25 ^ 2-1 = 625-1 = 25 ^ 2-1 ^ 2 = 625-1 = 624

Or in an equivalent way:


25 ^ 2-1 ^ 2 = (25-1) (25 + 1)

Answer:


h (x) = 25 ^ 2-1 = (25-1) (25 + 1) = 624
